DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1 for a preferred embodiment of the present invention,a mop is essentially comprised of a top plate assembly 1 and a baseplate assembly 2. The top plate assembly 1 includes a frame 11; a firstshaft 12 and a second shaft 13 are pivoted in parallel to each other tothe frame 11 by means of two linking members 15, 16 leaving both ends ofeach of linking members 15, 16 to expose out of the frame; one end ofeach linking member 15, 16 is each provided with a drive knob driveportion 151, 161 to drive its respective linking member 15, 16; acleaning member 14, which is a cleaning material referred to a dustpaper or a water permeable fabric in the preferred embodiment; thecleaning member 14 is mounted to the first shaft 12 while one end of thecleaning member 14 is coupled to the second shaft 13 for the cleaningmember 14 to execute linked displacement between both of the first andthe second shafts 12, 13 through the linking member 15 (or 16); aninterference member 19 disposed on the frame 11 is provided with aregulating portion 191, and the cleaning member 14 is secured in placeby moving the interference member 19 toward the first shaft 12 providedwith the cleaning member 14 in conjunction with the shaft 14 so toprevent the cleaning member 14 from displacement in the course of thecleaning routine. In the preferred embodiment, the regulating portion191 is pivoted to the frame by means of a linking member 17 with bothends of the linking member 17 exposed out of the frame and a driveportion 171 is disposed to each exposed outer end of the linking member17.

Now referring to FIG. 2, the base assembly 2 contains a base plate 21incorporated to a bottom of the frame 11; and a pad 22 (related to afoamed member or its equivalent) connected to where below the base plate11 to permit the cleaning member to travel along a partially exposedarea of the pad 22. Wherein, the cleaning member 14 creates a largerworking area in the course of the cleaning routine thanks to aidprovided by the base plate 21 and further to help the cleaning member 14firmly contact a floor in providing better cleaning results since thecleaning member 14 is supported by the pad 22.

As illustrated in FIGS. 3 and 4 showing interiors of the top assembly 1mounted with the cleaning member 14, the cleaning member is firstmounted to the first shaft 12 before being pivoted to the frame 11 withthe linking member 15 at where close to an edge of the first shaft 12;and one end of the cleaning member 14 is held to arrange the cleaningmember 14 along peripheral of the pad 22. In placing the cleaning member14 is connected to the second shaft 13 after it has wound around anotheredge of the base plate 21 that is not yet connected to the frame 11. Twopivoting portions 23 to mount the second shaft 13 is provided on thebase plate 21 to respectively receive both ends of the second shaft 13.In the preferred embodiment, an edge of the base plate 21 located atwhere closer to the second shaft 13 is connected to the frame 11, andthe linking member 16 penetrates through the frame and the second shaft13. Meanwhile, the interference member is pushed toward the second shaft13 to contain displacement by the cleaning member 14 to conclude anoperating mode that prevent the cleaning member 14 from exercising anydisplacement in the course of cleaning unless a user pushes away theinterference member to release interference of the interference member19 against the cleaning member 14.

In the event that replacing the cleaning member 14 is contaminated dueto contact the floor after having operated for a prolonged time, thelinking member 17 is turned by operating the drive portion 171 totemporarily release the interference member 19 and then turn the linkingmember 16 mounted on the second shaft 13 in a direction as indicated byan arrow as illustrated in FIG. 5 to pull out the cleaning member 14 toreceive the contaminated portion and to place a clean portion of thecleaning member 14 for further use. Upon having received thecontaminated portion of the cleaning member 14, the interference 19 isfixed in position once again to permit continuing the cleaning routine.The interference member 19 may be related to a catch mechanism operatingby compression.

The present invention by providing larger working area and increasesolid contact with the floor as the pad 22 supports the cleaning member14 realizes better cleaning results. Furthermore, the present inventionalso makes the operating process even easier by correcting the problemof frequent adjustment of a cleaning member due to smaller area of acleaning member contacting the floor as found with the prior art adaptedwith a roller.
